Do you ever just have days where you were already prepared to go to place to do something, but then you find out it was cancelled?

Well, that's just what happened. I got up quite early today, since I knew there was gonna be a quiz for a subject I had today. I was already prepared to go to school, but then I see in the group chat that our teacher announced that the quiz was moved next week. And I don't know, but I got frsutrated for a bit, since it was the only subject I had and I woke up early for it.

But now that I think about it, it might be a good thing it was postponed, since there would be more time to study for it. I guess I'll just let this frustration of mine go, so I'll be less stressed out about it.
